Hello,I am a 34 year old male, no history of heart problems, non-smoker, healthy.For the last 2 yrs I have had a constant pain on the left side of my chest (sometimes feel it in my left arm). I have 3 small children and find myself constantly concerned about my health. I have had blood work and EKGs done and everything is normal. My father and sister do have a history of panic/anxiety attacks. I have always thought that maybe I was suffering from something similiar and have tried to keep myself in check but it is becoming more and more frustrating as now I am worried that maybe I have a heart issue.If I decide to go on anti-stress/anxiety medication, shoud or would I see a change fairly quickly?

Chest pain on left side with pain in left arm has several reasons. Of course the most serious of them is angina or heart pain when heart is deprived of enough blood supply. However this is not constant like you have it for 2 years. Heart pain generally comes on after some exertion and subsides on rest.

Another possibility is a muscle or bone pain from the chest wall. This could be constant. Since you have it for 2 years, one must entertain a possibility of some spondylosis in the cervical vertebrae which could compress the spinal nerve root and cause a pain in front chest wall and arm.

However one must be certain and you definitely need to rule out heart issue by futher tests like Echo and stress test if your phisician deems it fit.
